Is it Cloning or Not? 32. For each of the following scenarios, indicate YES (it is cloning) or NOT (it is not cloning).
_ Sperm taken from a male goat is combined with a female’s egg in a Petri dish. The resulting embryo is implanted into the female’s uterus to develop. _ A sheep embryo, composed of 16 cells, is removed from the mother’s uterus and separated into individual cells. Each cell is allowed to multiply, creating 16 separate embryos, which are then implanted in different female sheet to develop to maturity. _ A cow with many desirable traits is stimulated with hormones to produce a number of egg cells. Each of these eggs is fertilized and implanted into a surrogate mother. _ In vitro fertilization _ Cell nuclei from an extinct woolly mammoth are placed into enucleated cow cells.
